The new Expert Reviews benchmarks, which can be downloaded for free, are designed to be run natively on Windows 7, Ubuntu 10.10 (a Linux distribution) and Mac OS X, so we decided to find out which operating system is the fastest.
We installed all three operating systems onto a 27in iMac with a 128GB SSD and a quad-core Intel Core i5-760 processor. The 64-bit versions of the operating systems were installed each time, and we used Bootcamp to load both Ubuntu and Windows 7 onto the iMac.
Our image editing test uses the ImageMagick command-line Convert tool to change 24-bit TIFF files to PNG format. It runs with the auto-level, auto-gamma, antialias and contrast options, simulating common operations performed on image files.
As you can see from the graphs, Ubuntu 10.10 is the stand-out performer.
